Thats a great question. i dont know how to answer it but i have had a similar question roaming my brain. Ok so , everything we make has had to start out from natural resources right? So shouldnt plastic or foam and such be able to go through some sort of cycle back through the earth if the components of the plastic or object came from the earth at some point.

For most applications, it would be very inconvenient for them to biodegrade. Tools, pipes, insulation, cups, etc. mustn't degrade. Plastics are very economical for these applications.Plastic bags, even, could be problematical unless you know how long they will last.Their chemistry makes them rather uninviting as an energy source for animals or fungi so they tend to just stay there.If only we could find a suitable bug to eat the stuff and produce foold/ oil from it.
